Image Version updated to avoid image pullbackoff error.

[ChinaBrahma]

Background

Previously, the Kubernetes manifest files used short image names (e.g., image: adservice). This configuration caused ImagePullBackOff errors when deployed on a remote cluster (like AWS EC2) because Kubernetes defaulted to looking for these images on Docker Hub, where they do not exist. The manifests were missing the specific container registry URL.

Fixes

Fixes ImagePullBackOff errors in kubernetes-manifests.

Change Summary

Updated all microservice deployment manifests to use the official Google Container Registry (gcr.io) paths and pinned them to version v0.10.1 to ensure stability.

| Service Name | Correct Image URL |
| adservice | gcr.io/google-samples/microservices-demo/adservice:v0.10.1 |
| cartservice | gcr.io/google-samples/microservices-demo/cartservice:v0.10.1 |
| checkoutservice | gcr.io/google-samples/microservices-demo/checkoutservice:v0.10.1 |
| currencyservice | gcr.io/google-samples/microservices-demo/currencyservice:v0.10.1 |
| emailservice | gcr.io/google-samples/microservices-demo/emailservice:v0.10.1 |
| frontend | gcr.io/google-samples/microservices-demo/frontend:v0.10.1 |
| paymentservice | gcr.io/google-samples/microservices-demo/paymentservice:v0.10.1 |
| productcatalog | gcr.io/google-samples/microservices-demo/productcatalogservice:v0.10.1 |
| recommendation | gcr.io/google-samples/microservices-demo/recommendationservice:v0.10.1 |
| shippingservice | gcr.io/google-samples/microservices-demo/shippingservice:v0.10.1 |

Additional Notes

The redis image remains as redis:alpine because it is a standard image available on the public Docker Hub.

Testing Procedure

1. Apply the updated manifests: kubectl apply -f ./kubernetes-manifests

2. Monitor pod status: kubectl get pods

3. Verify that all pods transition from ImagePullBackOff or Pending to Running state.

4. (Optional) Access the frontend via NodePort or LoadBalancer to confirm the application is live.
